Once BMR is calculated, it is typically multiplied by an activity level factor, which is based on factors such as exercise and whether a person has a sedentary or very active job. They are generally pretty similar, but the Katch-McArdle Formula, for example, which takes metabolic activity (resulting from differences between lean body mass and body fat) into account, can be more accurate for lean persons. Some of the more commonly used equations for estimating BMR include the Mifflin St-Jeor Equation, Harris-Benedict equation, and Katch-McArdle Formula. This includes physical characteristics such as age, gender, height, and weight. The calculation usually begins with an estimation of basal metabolic rate (BMR), which is based on the use of equations that have been developed for this specific purpose. TDEE is calculated based on the factors described above. Protein, for example, has a far larger thermic effect than dietary fat, since it is more difficult to process. It is sometimes estimated as 10% of food energy intake, but this can vary significantly depending on the type of food consumed. The thermic effect of food, also referred to as specific dynamic action, is the amount of energy required by the body to process and use food. These factors are more specifically referred to as the thermic effect of activity, and non-exercise activity thermogenesis (energy expended for non-sleeping, eating, or sports-like exercise). This includes deliberate exercise as well as other activities that a person may undergo as part of their job or typical daily activities. So, a 33 lb dog weighs 15 kg (33 divided by 2.2 15). To get your pet’s weight in kilograms, divide the number in pounds by 2.2. For example, if your pet weighs 15 kg, the calculation would look like this: 30 x 15 + 70 520 calories per day. In other words, it is the minimum energy needed to maintain a person's vital organs only.Īctivity level is a factor that is based on the amount of activity a person undergoes. Daily calorie needs 30 x your pet’s weight in kilograms + 70. More often, it is estimated using factors such as a person's basal metabolic rate (BMR), activity level, and the thermic effect of food.īMR is a person's energy usage rate while at rest in a temperate environment when the digestive system is inactive. TDEE is hard to measure accurately and varies day by day. It is the total energy that a person uses in a day. TDEE stands for total daily energy expenditure.

Very intense exercise: 2+ hours of elevated heart rate activity.

Intense exercise: 45-120 minutes of elevated heart rate activity.

Exercise: 15-30 minutes of elevated heart rate activity.The first step in calculating the caloric intake needed by an individual patient is. For more information and how the formulas are used in this calculator please refer to our Calorie Fact Sheet. The caloric density of a diet must be provided by the pet food.On this page, the term ‘calorie’ refers to kilocalorie unit of energy (symbol: kcal).

Regular weighing of the animal and adjusting their food to their need based on weight gain/loss, by a veterinary professional, is also critical. Using this information as a starting point, each individual dog should be fed to their ideal weight and body condition score.Please contact the manufacturer for the most accurate calorie content of their product and feeding guides. Some brands of pet food have lower feeding amounts due to the formulation of their diets and different levels of digestibility.However, if the calorie content is not provided on the label or the website of the manufacturer, you can use this calculator for a good estimate of the energy content of the product. Any analysis of the food provided by the manufacturer will be the most accurate for that specific product.This online calculator uses the Predictive Equations of NRC 2006 (the 4-step method) to estimate the Metabolisable Energy (ME) of prepared foods for cats and dogs (Fediaf Nutritional Guidelines).Please read before using this calculator:.
